Stainless Steel 304 is an 18/8 austenitic alloy, non-magnetic in its annealed condition but can become magnetic with cold working. It’s widely used due to its excellent ductility and weldability, making it ideal for deep-drawn parts. Stainless Steel 304L is a low-carbon version of 304, offering high resistance to oxidation up to 899°C. It is particularly suitable for use in as-welded conditions, even in challenging corrosive environments. Stainless Steel 304H contains a higher carbon content, making it ideal for high-temperature applications, providing excellent tensile and yield strength.
Our Stainless Steel 304/304L/304H Flanges are known for their outstanding qualities, including excellent welding and forming properties, resistance to oxidation and corrosion, toughness, and ease of cleaning. These attributes make them a versatile and reliable choice for various industrial applications.

FAQ
What is a 304L flange material?
A 304L flange is made from 304L stainless steel, which is a low-carbon variant of the 304 alloy. These flanges are available in pressure ratings from 150 to 2500 and PN6 to PN64, making them suitable for a wide range of applications. They can withstand temperatures up to 870°C, offering high durability and corrosion resistance in various industries.
What are stainless steel 304 flanges?
Stainless steel 304 flanges are components used to connect pipes, valves, and other equipment in a piping system. The SS 304 WNRF (Weld Neck Raised Face) flange is a specific type that features a raised face for better attachment and a welded neck for extra grip. These flanges are available in sizes ranging from ½ inch to 48 inches in diameter, making them versatile for various applications. They offer excellent corrosion resistance and are commonly used in industries like petrochemical, chemical, and food processing.
What is 304H stainless steel?
304H stainless steel is a high-carbon variant of the standard 304 stainless steel, designed for improved strength at elevated temperatures. It contains 0.04-0.10% carbon, compared to 304’s lower carbon content, which enhances its strength and resistance to creep and thermal expansion at temperatures above 800°F (427°C). This makes it suitable for use in high-temperature environments, such as in power plants and chemical processing.
